SpecsLib Calculated Metrics
These indicators are computed by SpecsLib from official manufacturer specs. They do not appear as such in any brand's documentation.
Area / Price6 sq ft/€
Square feet covered per euro spent. The higher the ratio, the better the area-to-price value.
Mowing density8,073 sq ft/hr
SpecsLib estimate (max area ÷ runtime), not published by the manufacturer: actual mowing time includes mapping, obstacle avoidance and recharging, so this figure likely overstates real-world throughput.
Slope score80/100 (Exceptional)
Normalised score based on the declared maximum slope (80%). 100 = mechanical limit, 0 = flat ground.

This model's technologies, against the evidence
What the brand promises, what independent tests actually found, and the limit to plan around.
Roborock PreciEdge
Brand Promise
An edge module brings the cut to around 3 cm from the boundary.
What testers found
Senses measured roughly 3 cm with the module against roughly 10 cm without it: the function does what it says. Two reservations. The module was sold separately, 1,799 SEK at the time of the test, and once fitted it drops obstacle clearance from 8 cm to 5 cm and reduces agility.
Watchout / Limitation
Depending on the version the module ships with the mower or is bought separately: the 3 cm figure assumes it is there. The same test found software still under construction, mowing patterns pushed back, and passages between zones needing close to a metre.
What the tests say
The flagship Roborock RockMow Z1 stands out with rugged AWD, independent suspension, and excellent slope handling. Testers praise the premium build and Smart Garden app. Drawbacks are the very high price point, early firmware navigation glitches, and dependency on clean RTK-GPS signals under tree canopies.
Strengths reviewers highlight
What public reviews and owner feedback most often praise.
- Exceptional AWD traction and off-road suspension (80% slopes)
- Twin 6-blade deck for high cutting output
- Self-leveling floating deck protects the cutting motor
- Full-featured Roborock app (multi-zone, AI avoidance)
Limits found in reviews
Consolidated watchouts identified by SpecsLib to help evaluate fit for your lawn and budget.
- Very high sticker price (premium positioning)
- RTK signal can drift in shaded areas
- Bulky in small yards
- Early-days bugs in no-go island handling
